so-called Europa Clipper, the Orbiter? Yeah, so the Clipper officially moved into phase B and for everyone not up on the exciting lifestyle, life cycle

So we're officially now developing the concepts behind the instrument.

It's kind of still on the drawing board, but one step further along.

If all goes well, when will this spacecraft leave for the

outer planets and what will it be writing? The Clipper would leave notionally in

2022 and notionally meaning if it continues to get funding from

Congress and actually makes it all the way through the development phase to

becoming a reality and it would right now launch on the space launch system that would put it on a direct
